BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a peeling machine for rods or tubes.

0002

[Prior Art] A pushing device on the inlet side, a rotating cutter head configured on the inlet side end face of a hollow shaft rotatably supported by a bearing in a machine housing, and a peeled workpiece removed from the peeler. Peeling machines of this type, which are equipped with a drawing device and at least two guide rails arranged in the housing of the peeler and extending parallel to the axis of rotation of the cutter head, are made from mainly hot-rolled metal circular cross-section materials. It is used to produce so-called polished steel materials. In this case, the cylindrical outer periphery of the rod-shaped circular cross-section material is peeled off by means of a rotating cutter head. The rod itself is guided axially through the central hole of the cutter head and through the peeler, protected against unintentional rotation. A rotating cutter head supports three or more inwardly directed cutters that peel the bar in a helical trajectory. This kind of peeling machine uses wire rod,
Used for rods and tubes. Conventionally used peeling machines work by having a pushing device consisting of two pairs of rollers on the inlet side of the cutter head and a clamping cart on the outlet side of the cutter head. , the clamp cart protects the rod from rotation and transports it. Peeling machines of this type also have guide devices just before and after the cutter head for centering the workpiece and damping vibrations resulting from the peeling process.

Modern peelers are capable of changing the feed, the rotational speed of the cutter head, and the finished diameter of the bar or tube to be peeled during operation. The feed rate and cutter head rotation speed can be changed relatively easily by controlling the drive motor, but the cutter adjustment to change the diameter of the bar to be stripped is done on a rotating hollow shaft and requires extremely fine adjustment. Exercise must be carried out.

Federal Republic of Germany Patent No. 2849576
From the specification, an installation for bar machining, in particular a peeling machine, is known which consists of several devices, in which the individual devices can be separated from each other for adjustment of the tools, and also for operation. can be assembled again. However, the disadvantage here is that the accessibility of the individual components of the peeler is not taken into account and the rigidity of the peeler is compromised by its mobility and insufficient fixation with the foundation.

[0005]

[Problems to be Solved by the Invention] It is an object of the present invention to provide a rigid structure for the entire subsystem of the peeler during operation, and to provide good accessibility to the individual components of the peeler during inspection. The object of the present invention is to improve a peeler of the above type so that the following is achieved.

[0006]

[Means for Solving the Problem] This object is based on the present invention, in which the pushing device and the peeler housing are relatively movable in the direction of the rotational axis of the hollow shaft, and the pushing device and the peeler housing are This problem can be solved by providing a removable tightening device.

[0007]

The essence of the invention lies in the combination of movability of the partial devices of the peeler for adjustment, maintenance and repair as well as for fixing the pushing device in the peeler housing during peeling operation. The tightening of the partial device takes place in the direction of feed of the workpiece to be peeled. All the subsystems that act on the workpiece to be peeled, from the feeding device to the housing in which the cutter head rotates, are passed through a guide rail and are clamped axially into one block to create an initial pressure. Added.

According to claim 2, it is advantageous to use a guide rail as the clamping means. Advantageously, the guide rail serves as a preloaded clamping bar.

[0009] According to an embodiment of claim 3, the guide device optionally arranged between the cutter head and the pushing device is also guided along the guide rail, so that the guide device is guided along the guide rail, and between the peeler housing and the pushing device. It is positioned and sandwiched between.

The embodiment according to claim 4 is preferably used. Diagonal here means that the two guide rails form an angle of 90° to 270° with the axis of rotation of the cutter head. The distance from the axis of rotation to the guide rail is of no great significance. However, the smaller the distance from the axis of rotation of the cutter head, the more advantageous is the force transmission. A guide and clamping rail is provided in the peripheral area of the peeler housing.

[0011] In one embodiment of the invention, the features of claim 5 are used. The housing of the cutter adjustment device is advantageously designed in the form of a ring and surrounds a rotatably journalled hollow shaft. This housing, as well as the pushing device and the optional front guide device, are guided along guide rails and are attached to the peeler housing, which supports a rotating cutter head in the interior during peeling operation. After loosening this attachment, the housing of the cutter adjusting device can be pulled away from the peeler housing axially opposite to the direction of workpiece feed, after the remaining devices located on the inlet side of the cutter head have been pulled apart. I can do it.

[0012] Advantageously, the embodiment according to claim 6 is used. An auxiliary transport device for extracting the cutter adjusting device from the peeler housing is thereby omitted. In this case, a device provided on the inlet side of the cutter adjustment device protects the cutter adjustment device from binding on the guide rail.

According to the features of claim 7, the size and weight of the pushing device are taken into account. As a result, a structural simplification is achieved for the guide rails guiding the pushing device, possibly the front guide device, and possibly the cutter adjustment device, which simplifies the pushing device, which has relatively large dimensions and a significantly high weight. This would not be possible without additional parallel rails.

The pushing device is the first of a series of partial devices guided along the guide rail. Claim 8
According to , this first device comprises a drive for moving the device guided in the direction of the guide rail. By selectively combining individual devices as claimed in claim 9,
The drive for the first device, usually a pushing device, can be used to provide the desired intermediate space between any adjacent devices for maintenance, adjustment or repair operations.

In order to be able to remove the individual devices laterally from the guide rail, the devices should be divided along the longitudinal direction. By longitudinal direction is meant a plane parallel to at least one of the guide rails.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be explained in detail with reference to drawings showing an embodiment of a peeling machine based on the present invention.

FIG. 1 shows a bar 21 to be peeled in a peeler 1. FIG. The peeling machine 1 includes a pushing device 2 equipped with conveying rollers 3 and 4 rotatably supported inside by bearings and rotationally driven by a method not shown, and a pushing device 2 equipped with a bearing 17 in a well-known manner.
, a cutter head 26 on a hollow shaft 6 housed in the machine housing 7 so as to be rotationally driven in 18, a rear guide device 10 which clamps the advanced rod by the rollers 16 in the skinned part, and an arrow As shown at 27, there is provided a clamp carriage 12 which is movable and which protects the bar 21 from rotation with clamp jaws 19, 20 and pulls it out from the peeler 1 at the end of machining.

The cutter head 26 is provided on the inlet side end face of the hollow shaft 6, and inside the cutter head 26, a conical sleeve 8 is disposed.
can be moved during the rotation of the hollow shaft 6 by rotation of the drive shaft 43, as shown by the arrow 9, in the direction of passage of the rod 21, as shown by the arrow 22. A plurality of cutter holders 14 are radially supported within the cone of the conical sleeve 8 and are adjusted radially relative to the rod 21 during axial movement of the conical sleeve 8 . The cutter 15 on the cutter holder 14 peels a layer of adjustable thickness from the rod 21 depending on the position of the cutter holder 14 and the conical sleeve 8 . Vibrations during the cutting process by the cutter head 26 are damped by the rollers 13 and 16 of the front guide device 5 or the rear guide device 10.

The pushing device 2 protects the rod 21 from rotation under the cutting torque introduced into the rod by the cutter head 26. In order to feed the rod 21 through the cutter head 26, a feeding force is applied based on the not shown drive of the rollers 3, 4.

The cutter adjustment takes place during the rotation of the hollow shaft 6 by means of a device 63 (see FIG. 2) which can be drawn into the peeler housing 7 in the direction of the rotational axis 62 of the cutter head 26. This cutter adjustment device 63
, 24, a support frame 36, an adjustment sleeve 37
, two conical sleeve bearings 38, 39, a conical sleeve 8, and an adjusting nut 41 screwed onto the external thread of the adjusting sleeve 37. The adjusting nut 41 carries on its outer surface a gear cutter 40 which, in the assembled state of the peeler 1 (see FIG. 1), is attached to the peeler housing 7.
It meshes with the gear 42 inside. In order to adjust the radial position of the paring cutter, the gear wheel 42 is driven in a manner not shown in detail by a drive shaft 43 as indicated by the arrow 9.

As shown in FIG. 3, the front guide device 5 has four guide rollers 13, 44,
45, 46, these guide rollers are arranged in a star shape around the bar 21 to be peeled and are adjustable radially relative to the bar 21 in the direction of the arrow 51 in a guide 61. The carriers of the rollers 13, 44-46 are supported outwardly by a cam ring 48 which, upon rotation in the direction of the arrow 50, displaces the guide rollers 13, 44-46 in the radial direction. The cam ring 48 is rotated by a servo motor 59 that drives a worm 49 that is held fixed in the housing 47 of the front guide device 5 and meshes with a gear cutout on the cam ring 48 .

The front guide device 5 is a rod 2 of relatively small diameter.
1 and can be removed from the peeler 1 laterally. For this purpose, the guide rails 23, 24
The housing 47 of the guide device 5 held in the housing 47 is divided. This division is effected by two caps 57, 58, the dividing surfaces 11, 52 of which intersect the housing 47 and the guide rails 23, 24. In order to take out the front guide device 5 laterally, the bolts 53 to 56 holding the caps 57 and 58 are removed, and the half-shell shaped caps 57 and 58 are removed.
is removed. The entire front guide device 5 can then be tilted and taken out from the peeler 1 laterally.

By means of guide rails 23, 24, the housing of all the devices involved in the cutting process, in particular the pushing device 2 and the front guide device 5, as well as the peeler housing, in which the hollow shaft 6 with the cutter head 26 is supported in a bearing manner. 7 are interconnected.

The length of the guide rails 23, 24 is adapted by preadjustment nuts 66, 67 to the length and number of devices to be tightened. The actual locking is carried out by cylinders 28, 31, which are connected to fixed wedges 29, 32.
This clamps the peeler housing 7 and the pushing device 2 together via the closing plate 60 of the peeler housing 7. When forming the initial load and locking of the entire peeler 1, the fixing wedges 29 engage in the through holes 30, 33 of the guide rails 23, 24. Peeling machine 1 is activated by the operation of cylinders 28 and 31.
The entire initial load and lock can be easily released.

The entire peeling machine 1 is tightened into one block by the guide rails 23, 24 and their locks, and an initial load is applied. The diagonal arrangement of the guide rails 23, 24 with respect to the axis of rotation 62 provides good force transmission and centering of the interconnected devices 2, 5, 63 and 1 or 7. Another important advantage is that the entire peeling machine 1 can be taken apart for maintenance, repair or inspection with minimal outlay. This removal can be carried out selectively, with the pushing device 2 alone being pulled back (i.e. towards the right in FIGS. 1 and 2) or the pushing device 2 in combination with the front guide device 5 or with another As a variant, the pushing device 2, the front guide device 5 and the cutter adjustment device 63 can be separated from the peeler housing 7, as shown in FIG. For this purpose, the above-mentioned device can be used, for example, with bolts 64, 6, depending on the desired separation.
The guide rails 2 are connected to each other by 5 and placed on the foundation.
3, 24 by a cylinder 34 which moves the pushing device 2 on a rail 35 parallel to 24.

The accessibility of the cutter adjustment device 63, particularly shown in FIG. 2 and made possible by the invention, is particularly advantageous since no crane or other heavy equipment is required for this purpose.
